Value = map(sensorValue, sensorMin, sensorMax, 255);. The Arduino map() function is an interesting beast. Very technically it works exactly as its documented to work, but not the way almost every . Arduino Garden Controller – Automatic Watering and Data Logging. The analog output only has an acceptable range between and 255. Therefore, the value has to be mapped within the acceptable range.

Overview of the map function on the Arduino platform, including how to read from a potentiometer and map values to a predefined range. The other day I was working on a new project with my trusty Arduino board.
